Stamp Duty Calculator

Stamp Duty Land Tax (SDLT) is a progressive tax, meaning you only pay each rate on the portion of the property price that falls within that band. For example, if you buy a property for £300,000 as a standard purchase, you pay 0% on the first £125,000, 2% on the next £125,000, and 5% on the remaining £50,000.

The rates changed significantly on 1 April 2025, when the temporary higher thresholds introduced during the pandemic were removed. The nil-rate band for standard purchases returned from £250,000 to £125,000, and the first-time buyer threshold dropped from £425,000 to £300,000.

First-Time Buyer Relief

If you are a first-time buyer purchasing a property for £500,000 or less, you benefit from reduced rates. You pay no SDLT on the first £300,000 and 5% on any amount between £300,001 and £500,000. If the property costs more than £500,000, the relief does not apply and you pay the standard rates on the full price. Both purchasers must be first-time buyers to qualify.

Additional Property Surcharge

Since 31 October 2024, the surcharge for additional residential properties increased from 3% to 5%. This applies if you already own a residential property and are buying another one, whether as a second home, holiday let, or buy-to-let investment. The surcharge is added on top of the standard rates for each band. You may be able to claim a refund if you sell your previous main residence within three years.
